had to kthe accompanying drawings, forming a part hereof.

My invention has relation to improvements in range-boiler stands; and it consists in the novel arrangement and combination of parts more fully set-forth in the specification, and pointed out in the claims.

`In the drawings, Figure l is an elevation showing a stand for a boiler of large crosssectional diameter. Fig. 2 is a similar view Fig. 3 is an enlarged elevation of the stand detached. Fig. 4 is a horizontal section on line 4 4 of Fig. 3.

Fig. 5 is a top plan of one of the legs, and Fig.

6 is a bottom planthereof.l

The object of my invention is to construct a range-boiler stand of a series of sections pivotally and adjustably jointed together so as to accommodate boilers of different crosssectional areas, one which is readily assembled and taken apart, one which is in a measure collapsible and capable of folding within a small compass, one which is sim le in coni struction, light, and durable, an one possessing further and other advantages better apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, l represents a series (preferably three) of angular members or bent legs substantially V-shaped in crosssection, the location of the angle a or bend of the member being preferably between onethird and one-half of the vertical height of the member-that is to say, a height measured along a line passin through the vertex of the angle and limitedlfliy two parallel horizontal planes passing through the opposite ends of the member. At the bend or angle a the sides of the member are somewhat widened beyond the dimensions on either side of the angle, thereby forming enlargements or lobes l 1,', which in the assembling of the parts are made to overlap one another, when they are subsequently pivotally connected by screwbolts 2, as shown, or by rivets, if desired.

-The several lobes 1 assembled in the manner indicated, form (for a stand having three tion, each member being capable of oscillationin the plane of its length about the pivotal connection with its adjacent members, as clearly obvious from the drawing, Fi 4. In practice the shorter arms ofthe mem ers are selected for the feet, though the principle of operation would be the same if the stand were to rest on' the longer arms. The ends 'of the longer arms or portions of the several members-that is, the portions above the angle a-.terminate in lips 3, projecting beyond the members proper, said lips engaging the base of the boiler B when the latter rests on the stand. The members 1 are virtually V- shaped channel-bars, and to prevent the edges of the feet from cutting into the floor the lowerends of the channels are closed by the terminal walls 4, which latter rest directly on the floor or on the supporting-surface for the stand.

It will be seen that the portions or arms of each member l subtending the angle a are disposed exteriorly to the axis of oscillation of the member and extend in the same plane from such axis, so that if the upper arm 1s oscillated outwardly the lower arm will oscillate inwardly, and vice versa. It therefore follows that the weight of the boiler supported on the upper arms or portions in its tendency to spread them apart at the same time exerts a corresponding tendency to draw the short arms together; but as the short arms rest upon the floor they cannot possibly approach each other or shift their position, for the reason that the same force which tends to spread the upper arms tends to force the ends of the lower arms into the floor. It therefore follows that once the boiler isset or placed down on the stand the several members of which the stand is composed become locked against any possible spreading and act as a unit in supporting the weight they are designed to carry. Obviously the princi le of construction here involved may be emp oyed 55 legs, as show-n) a triangular bond or connec- L kind of weight.
